SPECIFICATION forming part of Letters Patent No. 632,725, datedSeptember 12, 1899.

Application filed November 28,1898. Serial No. 697,664. (No model.)

To (0% whom it may concern.-

Be it known that we, CHARLES L. KLINE, Sn, and CHARLES L. KLINE, Jr.,citizens of the United States, residing at New York city, in the countyof New York and State of New York, have invented certain new and usefulImprovements in Mechanical Movements; and we do declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and to theletters and figures of reference marked thereon, which form a part ofthis specification.

Our invention relates" to improvements in machines in which heatisemployed to do mechanical workas, for example, by the expansion ofwater-vapor in steam-engines or the expansion of hot air or burnedmixture of air and gas in hot-air or gas engines, or to engines used inproducing electric light or power; and the object of our invention is toprovide attachments for engines of the kind set forth simple inconstruction, comparatively inexpensive to manufacture, that operatesmoothly and steadily in practical use, and which change horizontal orrectilinear motion to rotary motion.

To attain the desired end, this, our invention, consists in theconstruction, arrangements, and operation of parts herein set forth.

In the drawings which accompany and form a part of the specification,Figure 1 represents a side elevation, and Fig. 2 aplan view, of ourengine; Figs. 3, at, and 5 are views in detail of the parts of ourcam-disks.

Like letters and figures of reference indicate like parts in all theviews.

In order to explain our invention, we have shown the same as applied toan engine of the type in which the mechanical force arises from theelasticity and expansive action of steam, although manifestly our devicefor increasing force may be applied to any machines using an axle orshaft.

Referring particularly to the drawings, A denotes the cylinder of anordinarysteam-engine, and B the piston-rod, and C the connecting-rod orpitman, thereof.

The horizontal crank or primary drivingshaft D is journaled in boxes (1'and carries at opposite ends of same a crank-arm E, at the extremity ofwhich is a preferably rotary crankwrist or roller 8.

Our vertically-disposed cam-disks F consist of a triangular-shapedbase-piece and superimposed plates F, provided with inclined bearing edges f, which form interior channels or, ways f, in which one of ourwrists 6 works. These cams are mounted on two concentric secondarydriving-shafts G, which lie parallel with but considerably out of linewith and preferably lower than the shaft D and are journaled in boxes G.The shafts Galso carry gear-wheels H, which mesh with gear-wheels J,mounted on the power-shaft K, running in boxes and carrying the balanceor fiywheel M.

It is manifest that various omissions of some particulars could be madewithout materially affecting the essential features of our invention orthe operations of the remaining parts.

Obviously the elements of the structure described may be located at anangle to the plane in which theyare shown. We accordingly use the wordshorizontal, vertical, and the like in a relative sense.

In operation one of the crank-wrists c, Fig. egupon being rotated in thedirection of the arrow will ride up theinclined plate 2, approximatelyone-half the length of the plate, going to the end of the channel or wayf, as shown in thin broken lines, and then traveling back to thecommencement of the same, as represented in thick dotted lines, and thenleaving the same take a short circuit or route across to a point on theedge Z of the next plate near the beginning of another channel or way F.The wrist e rides to the end of the plate 1, and then travels back toabout the medium point of the plate, after which it leaves the plate andgoes to the edge 3 of the next plate. In like manner the othercrankwrist e, which lies in the same plane with the first one, but whichextends in an opposite direction from the shaft D, travels (while thefirst wrist c is taking its short circuit from the plate 2 to theplate 1) upward and back again through a channel or way f of theopposite cam, and then when it is about to make a short circuit acrossthe said cam the crank wrist e of the first cam will have reached theplate 1 and will then travel up its new channel or way. Thus fora periodboth wrists are in engagement with their respective plates of theopposite cams at the time when the crankarms are at or around theirdead-centers.

' Itwill be observed that our wrists e pass along the channels or ways falternately, but the shafts G have a continuous forward motion, and thatsaid wrists can never get out of the interior channels or ways formed bythe bearing edges f of the plates F.

Our cam-disks are provided with open centers and have bearing edges orfaces forming an equilateral triangle and are also provided withstraight channels or ways leading from the points of the triangle.

One of the principal advantages of this invention is that for a certainperiod or time bot-h crank-wrists e e are in engagement with theirrespective plates of the opposite cams. Another advantage is that theshafts G are set on a lower plane than is the shaft D, thus givingadditional leverage to the force exerted on the connecting-rod, whichleverage varies according to the angularity of the crank D and isgreatest when said crank D is at and around the ninety-degree pointitsgreatest point of efiiciency.

In cases where ourengineis used in producing electric light or power weuse a belt or other engaging means to connect the balance or fly wheel Mwith the pulley of a dynamo.

WVhat we claim as our invention, and desire to secure by Letters Patent,is-

1. In a machine, a crank-shaft provided with rotary crank-wrists lyingin the same plane, in combination with two cams provided with aplurality of bearing edges of certain inclination,andinterior channelsor ways; the

arms of said crank-wrists being provided with rollers engaging theinterior channels.

2. Acam-disk havinginteriorbearingedges or faces forming an equilateraltriangle and provided with straight channels or ways leading fromthe-points of the triangle.

3. Acam-diskhaving interior bearingedges or faces forming an equilateraltriangle and provided with straight channels or ways leading from thepoints of the triangle, in combination with a crank-shaft provided witha rotary crank-wrist.

4. In a machine, a crank-shaft provided with two crank-wrists located atopposite ends of the shaft, in combination with two cams constructed andarranged to engage said crank-wrists.

5. In combination, a crank-shaft provided with two crank-wrists, locatedat opposite ends of the shaft and two cams constructed and arranged toengage said crank-wrists, the shafts of the cams being out of line withthe crank-shaft.

6. In combination, a crank-shaft, and two oppositely disposed crank armsprovided with rotary wrists, and cam-disks provided with a plurality ofbearing edges or faces, the radii of the crank-arms and the cam-disksbeing of unequal lengths, whereby the leverage of the cams variesaccording to the angularity of the crank-arms.

In testimony whereof we affix our signatures in presence of twowitnesses.
